EYEGLASSES.

To all whom t may concern:

Be it known that I, Lao F. ADT, of Albany, in the county of Albany and State of New York, have invented new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and lexact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

rlhis invention relates to eyeglasses and particularly to that type in which the lenses move substantially in the plane of their optical aXes for the purpose of controlling the nose guards; an object of the present invention being to provide a mounting in which the springs, which position the nose guards, also serve for retaining the lens-attaching members and the bridge in cooperative relation.

To these and other ends the invention consists in certain improvements and combinations of parts as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification In the drawings: Figure l is a front view of the eyeglasses. Fig.Y 2 is a top view with the lenses in normal position. Fig. 3 is a like view showing the manner in which the nose guards separate upon the forward movement of the lenses. Fig. 4 is a perspective view of the bridge. Fig. 5 is a detail perspective view showing a lens-attaching member. Fig. 6 is a perspective view of the nose guard.

With more particular reference to the drawings, A indicates the bridge, B the lenses, C the lens-attaching members and D the nose guards.

The bridge A .is preferably made from fiat stock and comprises an arched nosebridging portion l; vertical bearing-portions 2 located near each end of the nose bridging portion, and each formed by rolling a forwardly extending lip on the flat stock into a sleeve; and spring portions 3 preferably formed from rearwardly-extending arms at the ends of the bridging portion7 by bending the stock of each arm widthwise and horizontally, first outwardly in t-he rear of the adjacent lens, then inwardly to form a loop in the rear of the adjacent lens, and finally forwardly to provide an arm extending to a point beyond the adjacent vertical bearing.

Specification of Letters Patent.

Application filed May S, 1907.

Patented Nov. 29, 1910. serial No. 371,747.

The lens-attaching members C are secured 'to the lenses B in any suitable manner and each is provided with a horizontal ear 4 which carries a vertical pin 5 arranged substantially in the plane of the lens and fitting in one of the vertical bearings 2. on the bridge. Then the bridge is connected to a lens-attaching member, one of the spring portions 3 thereof slidingly engages with a swinging part of the eyeglasses, for example, with the adjacent lens-attaching member, to retain the lat'ter and the bridge in cooperative relation. The pins 5 with the sleeves 2 being in the form of open bearings provide pivotal and detachable connections between the lenses and the bridge; and to prevent accidental disconnection of these parts, the springs 3 which effect the turning of the lenses, are employed for holding the parts together; the lens-attaching members for this purpose having means, as for instance, overhanging shoulders 7 with which the free ends of the adjacent spring arms 3 are adapted to engage to hold the parts together, and from under which the said arms are adapted to be moved to permit the adjacent lens-attaching member to be separated from the bridge.

The nose guards D may be of any suitable construction and may be connected to the mounting in any desired manner. However, it is preferred, to secure the noseguards to 'the mounting by the same springs 3 that connect the bridge and the lens-attaching members and, therefore, a horizontal portion 8 on each nose guard is fitted over a bearing pin 5 and is held against turning thereon by a suitable means as by a projection 9 which enters an opening l0 in the horizontal portion of the nose guard, the nose guard thereby being clamped between the adjacent lensattaching member and the bridge. These projections 9 extend above the nose guards so that they may engage the bridge in the rear of the pivotal connections and thus act as stops to limit the rearward movement of the lenses.

To remove or position the eyeglasses the lenses are moved in the plane of their optical axes by grasping them at their' outer edges and turning them relatively to the bridge, thus eecting the movement of the guards relatively to each other.

The springs 8 for effecting the interlocking connection between the parts and for turning the lenses are shown as forming parts of the bridge, as this is my presently preferred construction, nevertheless, I am aware that the springs 3 can be mounted in other ways and I therefore do not wish to be limited to the arrangement herein shown.

Having thus described my invention, what I claim is:

l. ln an eyeglass mounting, the combination with a bridge and a lens attaching member, of cooperating bearing members permanently carried by the lens attaching member and the bridge and detachably and pivotally connecting said parts, a spring rigidly secured at one end to one of said parts out otl contact with the bearing members to position the lens attaching member, and cooperating portions on the spring and the other parto the mounting for retaining the bearing members in engagement.

2. n an eyeglass mounting, the combination with a bridge, and a lens attaching member, orp bearing members permanently carried by the lens attaching member and the bridge and detachably engaging each other, a spring for turning the lens attaching member, carried by the bridge, out ot' contact with the bearing members, and cooperating portions on the spring and the lens attaching member retaining the bearing members in engagement.

3. In an eyeglass mounting, the combination with a bridge having a bearing thereon, of aV lens attaching member having a bearing member detachably cooperating with the bearing member on the bridge, a nose guard mounted also to swing relatively on the bridge and detachably engaging one ot' said bearing members, a spring for turning the lens attaching member and the nose guard relatively to the bridge, and cooperating portions on the spring and a portion ot the mounting acting to retain the bearing memi bers in engagement.

4. In an eyeglass mounting, the combination with a bridge and a lens attaching member, of a pivot pin permanently carried by one of said parts, a bearing on the other part detachably engaging the pivot pin, a spring rigidly secured at one end to one of said parts to position the lens attaching member, and cooperating portions on the spring and the other part ot' the mounting for retaining the bearing in engagement with the pivot pin.

5. In an eyeglass mounting, the combination of a bridge having spring arms, and lens-attaching members mounted to swing relatively to the bridge, held in1 normal positions by the spr'ing arms and carrying means to engage the spring arms near their free ends to hold the parts in coperative relation..

6. ln an eyeglass mounting, the combination of a lens-attaching member having a vertical pivot pin extending therefrom, a bridge having a bearing i tted on the extending portion of said pin, a nose guard also tted on the extending portion of the pin between the bridge and the lensattaehing member, a spring for returning the lensattaching member to normal position, and cooperating portions on the spring and another part of the mounting for retaining the bearing on the bridge and on the lens-attaching member in engagement.

7. ln an eyeglass mounting, the combination with a lens-attaching member, and a nose guard rigidly secured thereto, of a bridge having a spring arm connected with the lens-attaching member for returning the latter to normal position.

S. In an eyeglass mounting, the combination of a lens-attaching member having a shoulder, and a bridge to which the lens-attaching member is pivoted, having a spring arm adapted to engage below the shoulder to return the lens-attaching member to normal position and to hold the latter in cooperative relation with the bridge.

9. ln an eyeglass mounting, the combination ot a bridge formed of flat stock and having rolled lips forming vertical bearing sleeves, and lens-attaching members having bearing members for cooperation with the bearing sleeves.

lO. ln an eyeglass mounting, the combination with a pair of lenses, of a bridge on which the lenses are pivoted to swing in a substantially horizontal plane, having springs beyond the pivots cooperating with the lenses to turn them on their pivots and formed with loops deflected outwardly behind the lenses.

l1. in eyeglass mounting formed of 'Hat stock and comprising an arched bridging portion, forwardly extending spring arms formed by widthwise bends in the stock, and vertical bearings located between the forwardly extending arms and the bridging portions.
